In fashion, even gender knows no bounds. Last week, we were introduced to Casey Legler, the 6'2" female artist who is signed to Ford Models as a male model, and we're already well versed in the story of Andrej Pejic, the delicately featured male who works almost exclusively as a female model.

Hedi Slimane, the creative director of the label, has chosen Saskia de Brauw to front the campaign for his debut men's spring/summer 2013 collection. The 31 year-old from Amsterdam is the current model-of-the-moment and has already walked the catwalk for some of the world's biggest luxury brands.

Sakia de Brauw for Saint Laurent Homme spring/summer 2013 collection

But it's not de Brauw's first stint in menswear; she appeared in Givenchy's spring/summer 2013 menswear show (wearing the very same T-shirt that Rihanna donned as part of her 777 menswear marathon last week), her cropped hair and strong bone structure providing her with a fast-ticket to androgyny.

Slimane is well-known for his love of the gender-neutral aesthetic - his signature silhouette throughout his work at Dior Homme was that of super-skinny trousers and slim-cut tailoring, so much so that much of his menswear was bought and worn by women. It's not surprising, then, that his menswear for Saint Laurent is suitable for both men and women - indeed, the campaign even states that all of the clothes featured are available to both genders.
